The location of this recording was certainly memorable! The studio was in the house John Lennon and Yoko used to live in! It is also the house featured in the video "Imagine".
Ian found it fascinating wandering around the house and gardens. There were things like a Rolls, which had been through a crusher, huge plastic dinosaurs in the garden and even the phones still had extension buttons with "John" and "Yoko" on them. At the time, the house was (and possibly still is) owned by Ringo and was unused.
There is little information as to the tracks Ian played.
